西安市三桥新街—大庆路—长乐路工程交通与品质提升对策研究

Research on Traffic and Quality Improvement Strategies for the Xi'an Sanqiao New Street - Daqing Road - Changle Road Project

摘要:

随着城市化进程不断加快，既有城市主干道面临交通拥堵、慢行环境差、设施老化、管理粗放等多重挑战。西安市三桥新街—大庆路—长乐路作为东西向交通主动脉，存在交通设施老化、慢行系统断裂、通行瓶颈等问题。依托该道路综合治理工程，通过分析其现状问题、改造目标与技术策略，提出了“主路畅通、快慢分离、智慧绿色、以人为本”的总体改造目标，并系统梳理了该工程在道路断面优化、交叉口精细化设计、慢行系统连续性提升、公交地铁接驳改善、智慧交通设施配置等方面的实践做法。研究结果表明，针对高密度建成区的城市主干道，通过系统协同、多专业融合的精细化设计，能够在不大拆大建的前提下，有效实现主路畅通、快慢分离、出行安全与品质显著提高的综合效益，为同类城市道路更新改造提供参考。

Abstract:

With the continuous acceleration of urbanization, the existing urban main roads are facing multiple challenges such as traffic congestion, poor conditions for slow traffic, aging facilities and rough management. The Sanqiao New Street - Daqing Road - Changle Road is an east-west traffic artery in Xi'an with the problems of aging traffic facilities, discontinuities in the slow-traffic system and traffic bottlenecks. Relying on the comprehensive improvement project of this highway, by analyzing its current problems, reconstruction goals and technical strategies, an overall reconstruction goal of "unobstructed main roads, separation of fast and slow roads, smart and green, and people-oriented" is proposed. And the practical approaches of this project are systematically sorted out in optimizing road cross-sections, refining intersection design, enhancing continuity of slow-traffic systems, improving bus-metro connections and deploying smart traffic facilities. The research result shows that for the urban main roads in high-density built-up areas, the refined design of systematic collaboration and multi-disciplinary integration can achieve the comprehensive benefits such as unobstructed main roads, separation of fast and slow roads, travel safety and significantly improved quality under the premise of not major demolition and construction, providing a reference for the upgrading and reconstruction of similar urban roads.
